摘　　要：A special property of the S box of the block cipher Rijndael is found, which states that for any x 1, x 2, and Δ∈ SBYTE,if S(x 1)S(x 1Δ)=S(x 2)S(x 2Δ),then either x 1=x 2,or x 1=x 2Δ, where SBYTE denotes the set of all bytes. This property is helpful for mounting an efficient attack on Rijndael, that is illustrated by a simple example in this paper.A special property of the S box of the block cipher Rijndael is found, which states that for any x 1, x 2, and Δ∈ SBYTE,if S(x 1)S(x 1Δ)=S(x 2)S(x 2Δ),then either x 1=x 2,or x 1=x 2Δ, where SBYTE denotes the set of all bytes.
